Answer:

see below

Step-by-step explanation:

1/12 - 5/6 = -9/12

We need to get a common denominator of 12

1/12 - 5/6*2/2 = -9 /12

1/12 - 10/12 = -9/12

Since the denominators are the same, we can subtract the numerators

1-10 = -9

-9/12 = - 9/12

We can simplify -9/12 by dividing the top and bottom by 3

-9/3 = -3

12 /3 = 4

-9/12 = -3/4

Answer:

see below

Step-by-step explanation:

1/12 - 5/6 = -9/12

1st, we need to identify the Least Common Multiplier of 12 and 6

in this case, the LCM is 12

for 5/6 = (5*2) / (6*2) = 10/12

2nd, adjust the fractions based on the LCM

= 1 / 12  -  10 / 12

= 1 - 10 / 12

= -9 / 12 ---- simplify   -3 / 4

Peter has $4.80 in his piggy bank, consisting of dimes and quarters. If there are 33 coins in all, how many of each does he have
yaroslaw [1]

Answer:

10 quarters, 23 dimes

Step-by-step explanation:

Make dimes = d and quarters = q. Let the number of dimes and quarters add up to 33 and the value of the dimes and quarters add up to 4.80. The system of equations should look like:

  • d + q = 33
  • 0.10d + 0.25q = 4.80

Solve for d in the first equation. Subtract q from both sides.

d = 33 - q

Substitute d into the second equation.

0.10(33 - q) + 0.25q = 4.80

Distribute 0.10 inside the parentheses.

3.3 - 0.10q + 0.25q = 4.80

Combine like terms.

3.3 + 0.15q = 4.80

Subtract 3.3 from both sides.

0.15q = 1.5

Divide both sides by 0.15.

q = 10

Substitute this value of q into where we solved for d (d = 33 - q).

d = 33 - (10)

d = 23

Which option identifies the sampling technique represented in the following scenario? An ophthalmologist wishes to measure the r
Zielflug [23.3K]
The answer is C. Systemic random sampling.

By definition, systemic random sampling is a sampling technique where the respondents are selected according to a <em>random starting point </em>(this alone shows that the answer is C.) The researcher then chooses the sample interval, which is the difference between two consecutive  numbers in the progression. 

In this case, the starting point is 8 and the sample interval is 10.

The answer is C.
